Rifle Scope Information
Rifle scopes enable you to precisely aim a rifle at different targets by aligning your eye with the target at range. They do this through magnification by utilizing a series of lenses within the scope. The scope’s alignment can be dialed in to take into account different environmental factors like wind and elevation to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based on the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of contemporary rifle scopes have about 11 parts which are found internally and outside of the scope. These optic pieces consist of the rifle scope’s body, lenses, windage dials or turrets, objective focus rings, and other elements. Learn about the eleven parts of optics.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the perfect type of rifle optic is based on what type of shooting you plan on doing.
About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where estimations are small
- Experienced shooters who know their aim point “hold over” and “lead” correlations for their firearm
- Shooters who don’t mind the reticle is enlarged and requires more visual sight area than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle behind the magnification lens. This induces the reticle to stay at the very same dimensions relative to the quantity of magnification being used. The result is that the reticle dimensions adjust based on the zoom used to shoot over lengthier distances considering that the markings represent different increments which can vary with the magnification. In the FFP example with the SFP optic, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These sorts of glass are useful for:
- Long distance kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots occur within shorter ranges and spaces
- Shooters who choose a clearer optic sight picture without room used up by the larger size FFP reticle
Magnification for Optics
The level of scope zoom you need on your glass is based on the sort of shooting you plan to do. Pretty much every style of rifle glass supplies some level of zoom. The amount of magnification a scope provides is identified by the diameter, thickness, and curves of the lenses within the rifle optic. The magnification level of the optic is the “power” of the glass. This means what the shooter is observing through the scope is amplified times the power element of what can generally be seen by human eyes.
Single Power Lens Rifle Optic Details
A single power rifle scope and optic will have a zoom number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not fluctuate since it is set from the factory.
Adjustable Power Lens Scopes
Variable power rifle scopes use enhanced power. The power adjustment is accomplished using the power ring part of the scope near the rear of the scope by the eye bell.
Scope Power and Ranges
Here are some recommended scope power settings and the ranges where they could be successfully used. High power glass will not be as beneficial as lower magnification level glass because too much magnification can be a bad thing. The same goes for longer distances where the shooter needs to have increased power to see precisely where to properly aim the rifle.
Rifle Optic Lens Finishing
All modern-day rifle optic and scope lenses are coated. There are various types and qualities of glass coatings. Lens covering can be a crucial aspect of a rifle when looking into high-end rifle optics and scope systems. The glass lenses are among the most key parts of the glass as they are what your eye sees through while sighting a rifle in on the point of impact. The finishing on the lenses offers protection to the lens surface area and even improves anti glare capabilities from excess natural light and color presence.
HD Versus ED Scope Lens Coatings
Some glass manufacturers additionally use “HD” or high-def lens finishings which make the most of various processes, polarizations, rare earth compounds, and aspects to draw out numerous color ranges and viewable definition through the lens. This HD covering is often used with more costly, high density glass which decreases light’s opportunity to refract by means of the lens glass. Some scope suppliers use “HD” to describe “ED” implying extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration is often obvious around things with well defined outlines as light hits the item from certain angles.
What to Know About Single Finishing Versus Multi-Coating
Various optic lenses can also have various finishings applied to them. All lenses usually have at least some type of treatment or finish used to them before they are used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you paid for it.
Some scope manufacturers likewise make it a point to specify if their optic lenses are layered or “multi” coated. This indicates the lens has multiple treatments applied to them. If a lens gets multiple treatments, it can indicate that a producer is taking multiple actions to combat various environmental aspects like an anti-glare coating, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This additionally does not necessarily mean the multi-coated lens will perform much better than a single layered lens. Being “better” depends upon the producer’s lens treatment innovation and the quality of products used in building the rifle glass.
Anti-water Lens Finish
Water on a lens does not help with keeping a clear sight picture through a scope at all. Many top of the line and high-end scope companies will coat their lenses with a hydrophilic or hydrophobic coating.
Options for Mounting Rifle Glass on Long Guns
Installing options for scopes come in a few options. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also typically come in quick release versions which use manual levers which enable rifle operators to quickly install and remove the optics.
Rifle Glass Mounts with Hex Key Rings
Basic, clamp-on design mounting scope rings use hex head screws to install to the flattop style Picatinny scope mounting rails on rifles. These kinds of scope mounts use double independent rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are made for far away precision shooting. This form of scope mount is very good for rifle systems which require a long lasting, hard use mount which will not change despite how much the scope is moved about or abuse the rifle takes. These are the design of mounts you want for a faithful scope setup on a far away scouting or tournament rifle which will hardly ever need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used to stop the hex screws from backing out after they are mounted firmly in place. An example of these mounting rings are the 30mm type made by the Vortex Optics company. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and attach it to a different rifle. Multiple scopes can also be swapped out if they all use a similar design mount. These types of mounts are handy for long guns which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used in between several rifles.
Info on Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your costly optic by bringing about fogging and developing residue inside of the scope tube. Many scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Glass Gas Purging
Another component of avoiding the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the scope is less altered by temp alterations and pressure distinctions from the external environment which might possibly permit water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
